Description
Technical field
The present invention relates to refrigeration technology field, especially a kind of compression secondary injection refrigeration system.
Background technology
Industrialized continuous intensification makes human living standard be improved constantly, but also brings a series of serious side effect, such as global warming, power consumption, environmental pollution etc.These problems have badly influenced the safety of the mankind.Wherein Refrigeration Technique is the important component part of modern industry, is also the key areas of energy resource consumption, develops energy-conservation Refrigeration Technique and has become a kind of common recognition.
Ejector refrigeration system is a kind of energy-conservation refrigerating method, because it can utilize industrial exhaust heat, used heat, solar heat, the low-grade heats such as underground heat drive and produce refrigerating capacity.In addition spraying system flow process is simple, and moving component is few, and operation maintenance is convenient, small investment.Certain injection refrigerating system also has such as system effectiveness not high enough, affects the weakness such as large by heat source temperature.Therefore, by a compressor come assisted Extraction high evaporation device outlet refrigerant pressure, with reduce injector outlet cold-producing medium with by the pressure ratio of the cold-producing medium of injection.Final effect is the efficiency consuming part electric energy and improve injector, and the whole efficiency of final raising system.Therefore this kind of system not only has significant energy-saving effect, also has good application prospect.But this system flow is perfect not enough, efficiency also needs further lifting.
Summary of the invention
In order to overcome the deficiency that efficiency is lower, energy consumption is larger of existing compression secondary injection refrigeration system, the invention provides the new type of compression secondary injection refrigeration system with subcooler that a kind of efficiency is higher, energy consumption is less.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of new type of compression secondary injection refrigeration system with subcooler, comprise compressor, condenser, evaporimeter, generator and injector, the outlet of described evaporimeter is connected with the import of described compressor, the outlet of described compressor is connected with the driving fluid import of described injector, the outlet of described injector is connected with the import of condenser, the outlet of described condenser is divided into three tunnels, first via outlet is connected with the import of generator through pump, the outlet of described generator is connected with the working fluid import of described injector, described compression secondary injection refrigeration system also comprises first throttle device, second throttling arrangement and subcooler, second way outlet of described condenser is connected with the first import of described subcooler through first throttle device, first outlet of described subcooler is connected with the driving fluid import of described injector, 3rd way outlet of described condenser is connected with the second import of subcooler, second outlet of subcooler is connected with the import of evaporimeter through the second throttling arrangement.
Further, described first throttle device and the second throttling arrangement are choke valve, expansion valve or capillary.
Described subcooler is shell-and-tube heat exchanger, plate type heat exchanger, spray-type heat exchanger, immersion heat exchanger or double-tube heat exchanger.
Technical conceive of the present invention is: after the condenser, except pumped enter first via cold-producing medium except, separate two-way cold-producing medium in addition again.Wherein the second tunnel only needs to be throttled to intermediate pressure, and the refrigerating capacity producing temperature relatively high was used for cold 3rd road cold-producing medium.Be throttled to cold-producing medium direct injected device suction after evaporation endothermic in subcooler of intermediate pressure, because its pressure is higher, the pressure ratio of injector can be reduced without the need to compressor pressurizes, decrease the refrigerant flow by compressor, finally decrease compressor wasted work.And the refrigerating capacity transmission that said temperature is higher before gives the 3rd road cold-producing medium, the 3rd road cold-producing medium specific refrigerating effect is increased, and reach evaporating temperature after throttling, the refrigerating capacity that is system is final does not reduce.This system effectively can also reduce temperature when injector driving fluid is inhaled into, and improves the efficiency of injector.The above results can be summarized as: when the present invention strengthens the refrigerating capacity of injection refrigerating system output as much with routine, only need consume less electric energy.And owing to decreasing the flow of the refrigerating capacity flowing through compressor, less compressor can be used, reduce initial outlay.Also can reduce the temperature of injector driving fluid in addition to improve its efficiency.
Beneficial effect of the present invention is mainly manifested in: have higher efficiency than existing compression secondary injection refrigeration system, significantly reduce energy ezpenditure.
